The level sensors ROS 301 are designed to control three levels of electrically conductive liquids in one or in different tanks, including in explosive zones.
Level sensors ROS 301 are used in automatic control systems of technological processes, in signalling systems of technological and emergency levels of liquid media.
Level sensors ROS 301 meet the requirements of the Rules of the Russian Maritime Register of Shipping and the Russian River Register, have a version for delivery to nuclear power facilities.
The principle of operation of relay sensors is based on conversion of the change of electrical resistance between the sensor electrode and the tank wall into an electrical relay signal.
